Hussain sagar is situated in centre of Hyderabad city. A study was carried out on Hussainsagar lake to assess the impact of sewage pollution on the water quality of the lake. Water samples from various sites were collected and analysed for physico-chemical parameters to assess the quality of the lake system. The observed values of different physico-chemical parameters like pH, electrical conducitivity, total dissolved solids (TDS), total suspended solids (TSS), Nitrates, Dissolved Oxygen (DO), Chemical oxygen demanad(COD), Total Coliform, Fecal Coliform, Free Ammonia, Boron of samples were compared with standard values recommended by world health organization (WHO). The study revealed that due to discharge of untreated sewage into the Hussain Sagar, the water quality of Hussain Sagar has been severely deteriorated and the potable nature of water is being lost.
